Air pollution occurs a lot in Indonesia due to vehicle emissions, factory and household waste emissions, and air pollution caused by the accumulation and burning of waste at landfills. This day, for regulation and supervision of many things including air pollution, we can use the WSN (Wireless Sensor Network). WSN does not require cable installation so that the network is easily created and changed. The speed of data transfer in WSN tends to be stable. In this final project, the author created a WSN named XPollute. Xpollute is one of the wireless sensor networks that can monitor pollutants at landfills. Xpollute has high efficiency in its use of power because the required bandwidth is as small as data transmission needs. The measurement results by sensors can be displayed on web in the form of map infowindow, data tables or graphs. In addition, all devices in the Xpollute network are interconnected without the need for additional devices such as routers in 802.11. In implementating the wireless sensor networks there are several technologies that can be used, one of which is Zigbee with the Xbee Pro S2C module that will be used in Xpollute. In Xpollute, the author will design a very simple protocol in making mesh network implementation in Xbee Pro S2C to classify sent and received data on each node. The program that runs the logic of this protocol will be implemented into the microcontroller, Arduino. All data measured on the sensor will be converted into a packages that is easier to process. The Xpollute system will then measure the data on each sensor on the sensor node. Data received by sensor nodes will be used as data packages and sent to the server node for the data classification process before being forwarded to the database. The data in database will be visualized on the web by displaying data on maps, tables and graphs. After measuring several places with Xpollute, the author considers that the Xpollute system can measure data of specified parameters. However, some sensors, MQ-2 and MQ-7, have less sensitivity so that the measurement is still not appropriate. Xpollute can transmit data from sensor nodes to server nodes and push data to the database by providing data update information. Xpollute can also display the location of the sensor nodes on the map and display the measurement data infowindow on the web. The web also displays visualization of data in the form of tables and graphs base on system design.
